Outram PM4000

Outram PM4000

8 Input Power Quality Recording Analyser with waveform capture

The Power Master 4000 is a phase A powered, 3 phase power quality analyser with harmonics to the 50th, flicker and automatic reports.

About The PM4000

Full Power Quality Survey. No Fuss.

  • Pre-loaded PQ survey configuration means hook it up and start recording. No thresholds, no fuss, all the results you need.

Nuisance Tripping? Record without thresholds.

  • No thresholds need to be set for detailed event or waveform capture. Is it the supply or your installation causing the trip?

Safe, Long Term Recording.

  • A 600V Cat IV (1000V Cat III) analyser powered off phase A or 12Vdc charger. Remote comms available via our mobile app. PMGateway.
  • With FIFO mode and automatic download to USB, carry on recording until a specific event occurs, then collect your data.

Solve Customer Complaints Quickly.

  • Advise customers competently on voltage surges, dips, flicker or harmonics problems comparing any data streams in the Outram Research Ltd Software, Pronto for Windows, e.g. RMS voltage and Instantaneous Flicker, on the same graph.
  • Minimise customer disruption by finding problems quickly using Adaptive StoreTMRecord single cycle detail during events with no thresholds set.
  • Comprehensive, quick, consistent reports using graph and table templates in Pronto for Windows.

Preventative Maintenance

  • Monitor your power quality over time to detect any problems before they cause equipment failure or costly down time.

Check Pre and Post Equipment Installation

  • Benchmark before and check after the installation of new equipment to ensure quality of service has been maintained.

Monitor Your Motor Performance.

  • Are your machines deteriorating due to poor power quality? Observe the supply to your motors, checking for unbalance and harmonics in real time.

Key Features Include

  • Harmonics measured to IEC61000-4-7, Flicker Measured to IEC61000-4-15
  • Events captured to the EN50160 Standard.
  • Rugged, portable case is pad-lockable. Unit is IP65, reliable and easy to use.
  • 32 Channels of detailed recording down to a single cycle when an event occurs, without setting any thresholds, using our unique Single Cycle Adaptive Storage™ recording process..
  • Waveforms recorded on 8 inputs simultaneously. Select transients, notches, rings, sags, surges, THD, and/or TH Current. No need to set thresholds due to our Auto-Ranking Waveform Capture.
  • 13 Pre-loaded configurations are set for 3 and single phase hook ups with a variety of recording channels. These are selected for measuring voltage, current, real power, reactive power, apparent power, power factor, harmonics, flicker, unbalance, distortion and more.
  • The PM4000 runs off the voltage being measured. For voltages < 104V use an AC/DC 12V charger.
  • Battery back up provides 10 minutes resettable, timed ride-through in case of power outage. Automatic start up when power returns if within recording period or in FIFO mode.
  • PM4000 user interface, PMScreen, is available as an Android mobile phone app. This phasor diagram display is a graphical touch screen interface that enables configuration, ensures correct hook up, provides suggestions upon detecting errors and advises if a current sensor is the wrong way round.
  • HELP in PMScreen guides users through configuration and hook up – just hold down the relevant button.
  • Safety: 600V Cat IV, 1000V Cat III, pollution level 2 unit. Compact, will fit in most panels and allow the door to be closed. Safely review data via Bluetooth while the unit is locked away in a cupboard.
  • Hook-Up Guide and Configuration Guide as well as a manual help you get your set-up right every time.
  • Data analysis is easy with our comprehensive,  in-house software Pronto for Windows (included in your kit). Data also available as .xls, .csv, PQDIF.
  • Fused voltage leads and internally fused voltage inputs protect this valuable equipment.
  • Capable of storing up to 127 configuration or data files.
  • Field programmable software and firmware updates.
